7 Claims.

The present invention relates to indirect lighting fixtures, and is moreparticularly directed toward indirect lighting fixtures employing twounlike sources of light, such for example as a mercury vapor lamp and aplurality of incandescent lamps.

The present invention contemplates an indirect lighting fixture havingan upwardly opening enclosing shade or bowl which may be. transparent oropaque, and which surrounds a central vertically disposed mercury vaporlamp and a plurality of incandescent lamps. The lamps are carried inlamp sockets supported in a unitary element adapted to carry the shadeand to be supported by a hanger.-

According to the present invention, the incandescent lamp sockets andthe mercury vapor lamp socket are secured to a unit wherein theincandescent lamp sockets are connected to one current connector, andthe mercury vapor lamp socket is connected to another connector, andthese connectors are supported in such a way as to be convenientlyconnectible to cooperative connectors carried by the supporting hanger.

The present invention also contemplates lighting fixtures havingsocket-carrying units adapted to support upwardly extending lamp bulbsand means for supporting these units so that they can be tilted tofacilitate re-lamping.

The support for the tiltable unit includes hinge connections anddetachable electrical connectors so that the fixture may be readilyassembled and adjusted.

Other and further objects will appear as the description proceeds.

The accompanying drawing shows, for purposes of illustrating the presentinvention, one of the many embodiments in which the invention may takeform, it being understood that the drawing is illustrative of theinvention rather than limiting the same.

In the drawing a Fig. 1 is a vertical sectional view taken on the lineI-I of Fig. 2, the dot and dash lines indicating the position of theparts when swung downwardly;

' Fig, 2 is a top plan view through the lower unit, parts being brokenaway;

Fig. 3 is a section on the line 3-3 of Fig. 2;

and

Fig. 4 is a fragmentary sectional view through a modified form ofconstruction.

In the form of construction shown in the drawing, the fixture is apendant one and hangs from a support It. This support carries a hangercomposed of four tubular arms I I. Two of these arms are provided withchain links indicated at I2, and two of the arms are provided with fixedloops I3. Pairs of wires extend down through two of the tubular arms II,as indicated at I4. These wires terminate in female connectors, one ofwhich appears at I5.

The loops I3 and links I2 are adapted to receive hooks I6 secured inholes II in a plate I8. The plate I8 is preferably in the form of asheet metal stamping centrally apertured, as indicated at I9, andprovided with an annular trough or recess 20. The downwardly andoutwardly sloping wall of this recess is apertured, as indicated at 22,to receive attaching screws 22' for lamp sockets 23. It is apertured at24 to permit the wires to pass to the socket. These sockets supportincandescent lamp bulbs 25, as indicated.

The plate I8 may be reinforced by a ring 25, if desired, and carriesthree downwardly extending rods 26. These rods support a casting 21 towhich is attached a central upwardly opening lamp socket 28. This socketis adapted to receive a mercury vapor lamp 29 inserted through theopening I9 in the plate I8.

The socket 28 is connected by a pair of wires indicated at 30 with amale connector 3I fixedly secured to the stamping I8. This connector hasupwardly extending contact blades indicated at 32. The current supplywires for the incandescent lamps are connected to a similar connector 33having contact blades 34 and adapted to cooperate with the correspondingfemale connector carried by the hanger.

The casting 21 carries a threaded stud indicated at 3.5, and this isadapted to receive a knob 36 which holds the socket cover 31 in place.The socket cover extends upwardly and outwardly so that its periphery isadjacent the periphery of the plate I8. The socket cover thereforecovers and conceals the bottom of the plate and the wiring to the lampsockets. It also supports a shade such as the opal glass hemisphericalbowl indicated at 38, or the sheet metal bowl indicated at 39. Thesebowls are downwardly removable so as to facilitate assembly anddisassembly of the lighting fixture.

In manufacturing these fixtures, the socketcarrying unit is completelyassembled with the wires and connectors, and the current supply wireswith connectors are provided in the hanger. To assemble the fixture, itis merely necessary to hook the socket-carrying unit to the lower endsof the hanger arms and connect the electrical connectors. When desired,the lower part of the fixture may be allowed to hang down on two of thehooks, as indicated in the dot and dash lines of Fig. 1. This iseffected without disconnecting the electrical connectors. The lamp bulbsswing between the arms of the hanger so as to cause no interference.

It is obvious that the invention may be embodied in many forms andconstructions within the scope of the claims,'and I wish it to beunderstood that the particular form shown is but one of the many forms.Various modifications and changes being possible, I do not otherwiselimit myself any way with respect thereto.
